“Was skeptical about the back pocket, but my phone stayed completely put during a hilly 6-miler. The support is fantastic too, no bounce and more importantly, no chafing under my pack. I'm buying another one.”

5/5
Paige M.

“I run in the Texas heat and this is the first high-impact bra I've owned that doesn't feel like a swampy straightjacket after 30 minutes. It's supportive, yes, but the mesh panels are a game-changer for staying cool.”

5/5
Brooke H.

“Wore this for a 4-hour trail run and forgot it was there. The band didn't ride up, the straps didn't dig in. Just solid, comfortable support. Well worth the price.”

5/5
Hailey V.

“Perfect balance of cushion and breathability. My feet stayed dry and blister-free through a muddy 20-miler. Plus, they didn't stink at all afterwards. Merino wool is magic.”

5/5
Caleb R.

“I'm tough on my gear, and these have held up to rocky trails and countless washes. They've got this soft, cushioned feel but my feet never overheat. Ditching my old synthetic socks for good.”

5/5
Grayson T.

“I was so worried about my feet for my first 50K. A friend recommended these and they were lifesavers. Not a single hotspot, even with two creek crossings. Incredible.”

5/5
Sierra K.

“I wanted a lighter sock for summer and these are it. Super breathable, light, and the little heel tab is brilliant—no slipping down into my shoe. My feet stay way cooler.”

5/5
Quinn D.

“Great sock for when you want protection without the height of a crew sock. The fit is snug, the cushioning is just right, and they feel fast. No issues with rubbing on my Achilles.”

5/5
Preston A.

“I use the crew version for ultras, but these ankle socks are my favorite for anything under 15 miles. They just disappear on your feet. Same great merino comfort, less sock.”

5/5
Kendall B.

“Wore these for a race with a ton of vertical gain and my calves felt noticeably fresher on the final climbs. The compression is supportive without being suffocating. Great race sock.”

5/5
Jaxon L.

“I have incredibly sweaty feet and most socks are soaked after an hour. The Coolmax fabric is insane, it just pulls the moisture away. My feet stayed dry through a whole humid afternoon run.”

5/5
Cassidy F.

“The perfect blend of support and cooling. I was looking for a compression sock that wasn't crazy hot. This is it. Performed flawlessly during a hot marathon.”

5/5
Wyatt S.

“Literally saved my runner’s knee. I was getting sharp knee pain on every downhill. This sleeve supports exactly where I need it. Back to pain-free trails.”

5/5
Skylar J.

“My legs feel more stable and less fatigued on long runs. The top band actually stays put and doesn’t roll down.”

5/5
Holden P.

“Post-workout recovery is way better when I wear this for a few hours. Next day soreness is noticeably lower.”

5/5
Avery G.

“This is the first vest I’ve owned that truly doesn't move. Fully loaded and still zero bounce or chafe. Blown away.”

5/5
Lincoln W.

“Pocket layout is brilliant. Phone secure, flasks easy to grab, gels up front—fuelling without breaking stride.”

5/5
Morgan T.

“As a bigger guy, the adjustable straps are a lifesaver. Fits perfectly without feeling restrictive.”

5/5
Easton H.

“Came with everything out of the box and performed perfectly on race day. Great value.”

5/5
Peyton R.

“So lightweight and breathable I forgot I had it on. Carried all I needed without feeling weighed down.”

5/5

Frequently Asked Questions

What makes ALPYN gear different from other brands?

ALPYN was born on the trail. We focus on solving the real problems that runners and adventurers face: discomfort, distractions, and gear that just doesn't last. We combine premium, high-performance materials like merino wool and Coolmax® with athlete-tested designs to create gear that is so comfortable and functional, you'll forget you're wearing it.

What materials are used in ALPYN products?

We select the best material for each specific job. Our products feature a range of high-performance fabrics:

  • Merino Wool Blends: For our socks, we use premium, ultra-fine merino wool for its natural temperature regulation, odor-resistance, and soft, blister-free comfort.
  • Coolmax® Technology: In our performance socks, we use Coolmax® fibers for their unmatched ability to wick sweat and keep you cool and dry in the heat.
  • Performance Synthetics: Our bras, vests, and sleeves use lightweight, durable nylon and spandex blends engineered for a chafe-free, zero-bounce fit with maximum breathability.

How do I choose the right size for my gear?

A perfect fit is critical for performance. Each product page has a detailed sizing chart to help you find your ideal size. For our socks, we base sizing on your shoe size. For our bras and compression sleeves, we recommend taking your specific measurements for the most accurate, supportive fit. If you're ever between sizes, our product pages offer a recommendation, but feel free to contact our support team for a personal consultation.

Is ALPYN gear good for sports other than running?

Yes, absolutely! While our gear is engineered with the demands of trail running in mind, its focus on comfort, support, and durability makes it perfect for a wide range of high-impact activities. Our customers use ALPYN products for hiking, gym workouts, cycling, and other endurance sports where performance and comfort are key.

5. How should I wash and care for my ALPYN gear?

To maximize the lifespan of your ALPYN products, we generally recommend:

  • Machine wash cold on a gentle cycle.
  • Hang-dry for longevity (you can tumble dry on low if needed).
  • 🚫 No bleach or fabric softener, as these can degrade the performance fibers.

Please refer to the specific care instructions on each product page for detailed recommendations.

What is your guarantee or return policy?

We stand by every product we make with our 99-Day Risk-Free Trial. We encourage you to put our gear to the test on your runs and adventures. If for any reason you're not completely satisfied with the fit, comfort, or performance within 99 days, you can return it for a full refund or exchange—no questions asked.
